We’ve made 49 changes since releasing Beta 4 a week ago. RC means we think we’re done, but with millions of users and thousands of plugins and themes, it’s possible we’ve missed something. We hope to ship WordPress 4.5 on Tuesday, April 12, but we need your help to get there.

Developers, please test your plugins and themes against WordPress 4.5 and update your plugin’s Tested up to version in the readme to 4.5 before next week. If you find compatibility problems, we never want to break things, so please be sure to post to the support forums so we can figure those out before the final release.
